Tetra­ethyl­ammonium tricarbonyl­chlorido(isoquinoline-1-carboxyl­ato-κ(2) N,O)technetate(I)

The asymmetric unit of the title compound, (C(8)H(20)N)[Tc(C(10)H(6)NO(2))Cl(CO)(3)], consists of two crystallographically independent technetium complexes related via a pseudo-inversion centre and two tetra­ethyl­ammonium cations. The Tc atoms have slightly distorted octa­hedral coordination geometries, and they are linked with the cations by inter­molecular C—H⋯O and C—H⋯Cl hydrogen-bonding contacts, forming two-dimensional columns, which lie approximately parallel to (001) in the crystal structure. The isochinolate (isoquinoline-1-carboxyl­ate) ligands link the columns by partial π–π stacking [centroid–centroid distance 4.3733 (11) Å], forming a three-dimensional network structure.
